Question 7 When describing how power and work are similar you would want to mention that

you must know time to determine both work and power
you must know force in order determine both work and power
you must know energy in order to determine both work and power
you must know velocity to determine both work and power

How would doubling the made of an object change the objects potential energy

Use the right-hand rule for magnetic force to determine the charge on the moving particle. this is a charge.

In a heat engine if 1000 j of heat enters the system the piston does 500 j of work, what is the final internal energy of the system if the initial energy was 2000 j? 1. write the equation 2.list out your known variables 3.plug the numbers into the equations 4.solve 5.write your solution statement that includes initial energy and final
